RT 230 Ch 8
Pathology for RTs
| Question | Answer |
|---|---|
| Aneurysm | a localized "ballooning" or out-pouching of a vessel wall which occurs when the vessel wall has been weakened |
| Arteries | are blood vessels that carry blood away from the heart |
| Atherosclerosis | is a degenerative condition that affects the major arteries of the body,often termed hardening of the arteries |
| Atrial septal defect (additive) | most common congenital heart defect, when the foramen ovale does not close at birth, an opening remains between the right and left atria |
| Capillaries | microscopic vessels that connect the arteries and veins which are responsible for the exchange of substances necessary for nutrient and waste transport |
| Cardiomegaly | enlarged heart |
| Congestive heart failure (additive) | occurs when the heart is unable to propel blood at a sufficient rate and volume |
| Coronary artery disease (CAD) | disease of the arteries of the heart often resulting from deposition of atheromas in the arteries supplying blood to the heart muscle |
| Diastole | the subsequent relaxation of the myocardium |
| Dissecting aneurysm | results when the intima tears and allows blood to flow within the vessel wall, thus forming an intramural hematoma |
| Doppler echocardiography | is an adjunct, noninvasive procedure used to study peripheral vasculature |
| Embolization | interventional angiography procedure in which devices such as coils are used to intentionally clot off vessels |
| Fusiform aneurysm (abdominal aortic aneurysm) | when bulging includes the entire circumference of the vessel often found in the distal abdominal aorta |
| Heart | acts as a pump to propel the blood throughout the body via the circulatory vessels |
| Infarct | an area of ischemic necrosis |
| Ischemia | a local and temporary impairment of circulation caused by obstruction of circulation |
| Pulmonary embolus (PE) | a mass of foreign matter present in a pulmonary artery or one of its branches |
| Right and left ventricles | two lower chambers of the heart |
| Saccular aneurysm | a localized sac affecting only a part of the circumference of an arterial wall |
| Stent | may be placed in a narrowed vessel to maintain its patency |
| Systole | the contraction of the myocardium |
| Thrombolysis | a procedure in which a high intensity anticoagulant, such as streptokinase, is dropped over a period of hours directly onto a clot to dissolve it |
| Thrombus | a blood clot that obstructs a blood vessel |
| Veins | blood vessels that carry blood to the heart |
| Venous thrombosis | the formation of blood clots within a vein |
| Heart, arteries, capillaries, and veins | The cardiovascular system consists of what? |
| Pulmonary circulation | transports blood between the heart and lungs |
| Systemic circulation | transports blood between the heart and the rest of the body |
| Right and left atria | 2 upper chambers of the heart |
| Endocardium(inner), myocardium(middle), epicardium(outermost) | What are the 3 layers of the heart? |
| Pericardial sac | The heart is inclosed in what? |
| Electrocardiography | graphically displays electrical activity of the heart |
| Myocardial infarction (heart attack) | caused by an acute thrombus of the coronary arteries |
| right ventricle | The heart chamber located most anteriorly and forming the anterior border of the cardiac shadow on a lateral chest xray is? |
| left atrioventricular valve | The bicuspid valve is also know as the? |
| 10 | How many posterior ribs should be visible on a good inspiration PA chest xray? |
| deep veins of the lower extremities | Venous thrombosis most often affects the? |
